It’s easy, made with real ingredients, and the results are always so good.
Why we love it:
Protein-packed: If you need to get that extra protein fix in for the day, this is a great dinner to make! Steak always hits the spot (especially if you ask my husband 😉).

I love whipping out my slow cooker for a lot of reasons, namely because it just makes life so much easier.
Ingredients Needed for Slow Cooker Mongolian Beef
Steak – Sirloin is my favorite cut to use when making Mongolian beef. It’s relatively inexpensive and because we’re slow cooking it, we can get away with a leaner steak. Soy Sauce – Low-sodium soy sauce is preferred. Tamari or coconut aminos will also get the job done. Apricot Jam – This adds a subtle, natural touch of sweetness that just can’t be beat! Hoisin Sauce – This dark, thick, rich sauce adds both saltiness and sweetness to the dish. Cornstarch – This is used to thicken the sauce. Measure with care! Veggies – Freshly sliced onions and bell peppers add just the right amount of crisp, fresh texture and flavor to this savory dish. Garlic and ginger – For the best flavor and aroma, make sure both of these ingredients are fresh!

Variations and Substitutions
Swap the steak: Sirloin is my favorite steak to use, but you can use really any other cut of steak that you prefer! The low and slow cooking process will turn any cut of steak into a tender masterpiece. Add more vegetables: You can make this dinner as nutritious as you’d like! Feel free to toss in some broccoli, mushrooms, green beans, or whatever else sounds good to you. Make it spicy: Sprinkle in some crushed red pepper flakes if you’re craving some heat. You can also mix in some chili garlic sauce to spice things up! Add the peppers and onions whenever: If you don’t like your peppers and onions soft, feel free to just toss them in for the last hour – I put mine in for the whole cooking time. Do whatever works for you, and whatever your family prefers.
How to store Mongolian Beef
Once it cools to room temperature, you can store any leftovers you have in an airtight container in the fridge for 2-3 days. To reheat, add a splash of water or broth and pop it in the microwave for 30 seconds at a time, stirring each time it stops, until heated all the way through. You can also add a splash of liquid and reheat it on the stovetop.
Can I freeze Mongolian beef?
Yes! Let cool fully to room temperature, then transfer everything to a freezer-safe airtight container. Freeze for up to 3 months When you’re ready to enjoy the Mongolian beef, you can let it thaw in the fridge, or place it in a large skillet with a splash of water or broth. Cover and heat on low until warmed through. Keep in mind that the vegetables will be quite soft after freezing, so you may want to leave them out until you are ready to serve.
Do I have to sear the steak first?
I personally prefer to sear the steak first so the juices don’t water down the sauce too much. However, you can save yourself a little effort and cleaning by just tossing the steak directly into the Crockpot (this is how I made this recipe originally!).

Serve Mongolian beef over this baked rice or the noodles of your choice. You want something to catch all of that amazing sauce so not a single drop goes to waste!
